Transit at IXP & next-hop-self

And college started after pretty good holi holidays. Again having bit painful time due to hot weather and this is just start of summers. Well all I can hope is that there won’t be voltage issues in village again (like last time). And just to make sure on that part - I have put 2 RTI’s asking Power department about their preparation details. :)

Anyways coming on blog post topic for the day - the effect of “next-hop-self” at an IXP when there are peers as well as transit customers of a network. Just to be clear in start - this post will stick to technical side of it and without going into IXP policy side of it.

Midnight system screwup (and fix!)

I was just working (and playing music!) and realized that “Movie player” package given on default Ubuntu installation isn’t of much use. 

Decided to uninstall it, next needed arping for some test and installed it (via default debian repository). Something crazy happened here. I opened something on personal server and it gave DNS error. I shot couple of digs from terminal and all timed it. I was scared to hell thinking of DNS failure on personal domain which is very very unlikely since I am using multiple DNS providers and close to a dozen of servers serving DNS zone.
